hugetlb: pull gigantic page initialisation out of the default path
As we can determine exactly when a gigantic page is in use we can optimise
the common regular page cases by pulling out gigantic page initialisation
into its own function. As gigantic pages are never released to buddy we
do not need a destructor. This effectivly reverts the previous change to
the main buddy allocator. It also adds a paranoid check to ensure we
never release gigantic pages from hugetlbfs to the main buddy.
